It had been a successful and demanding first day of shooting. With the curtain lifted, we had taken full advantage, leaning into the wind and reaping rewards. Upon returning to the guesthouse, we did not have time to relax, as the Kp-index for the evening rekindled excitement. I downloaded and backed-up my day’s images and joined the growing table for dinner. All chatter focused on the wind and atmosphere created around our recent locations, but soon our talk shifted to aurora.
Icelandic photo tours and workshops promise* aurora. There is always an asterisk, only Nick and Thor deliver aurora (read-on).
The Kp-index is an index of global geomagnetic activity derived from measurements from ground-based magnetometers at high, northern and southern latitudes. Based on real-time measurements, the NOAA Space Weather Prediction Center provides a Kp-index forecast helpful in protecting sensitive technology. This is important stuff. But, even better for photographers, the Kp-index is also a predictor of aurora. Several of us had mobile apps loaded for alarm notifications of indices, say, greater than 4.0. The scale is 0.0 to 9.0. I’d need an index greater than 7.0 or 8.0 to have any chance of seeing aurora in Nevada (it happened once), but when it’s 4.0 in Iceland, you get ready for some night photography.
Nick, walking the hallway between after-dinner recons on the snow-buried porch, said to the be at the van at 9 PM. Then he said, “8:30”. Then, “8:00… Um, no, let’s just go now!”, a green glow leaking beyond a low, receding band of clouds in the northern sky above the guesthouse. With or without the predicted index, aurora activity remains elusive. The sky can light up at any moment and with the storms of the past few days, we knew the clouds could mask everything without any warning.
A few team-members had decided by dinnertime that the day had been plenty fun. The wind and blowing snow can drain motivation—the wind had yet to let up and we were headed back into the gale, and jet-lag may still been wearing on those that just arrived. Six of us climbed back into the van, ready for a long, cold night.
